Detailed explanation-1: -Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal.
Detailed explanation-2: -Earth’s layer’s names are: Crust: the outer layer of rock on which humans and animals live and plants grow. Mantle: a semi-solid magma layer consisting of iron, magnesium, and silicon. Core: centrally located solid mass of metal (inner core) and a liquid mass of iron and nickel (outer core).
Detailed explanation-3: -The inner core of the Earth has temperatures and pressures so great that the metals are squeezed together and are not able to move about like a liquid, but are forced to vibrate in place as a solid. The inner core begins about 4000 miles beneath the crust and is about 800 miles thick.
